There is actually a "hidden" quest for it as a Cleric. It gets started when you help some lady get a Cleric tome, then she analyzes it, and you can get a quest to dig further. I only got the first part as a Berserker, but as a Cleric I got a bit more info after some time (she tells you where to find the 1st out of 9 parts or some such thing).
At any rate, there are no teleporters there. It does contain a few interesting revelations though.
